it means that the magistrates feel it may attract a sentence of over 6 months, so it is considered serious.
each court has Witness Support officers. if you have to give evidence (if he pleads not guilty) you might want to check in with them. if he pleads guilty your statement will be read out in court. the police also have Victim Support who may be able to answer your questions.
don't forget what he did to you. too many women "forgive" (he was drinking, it was the first time, he'll never do it again, he's really sorry, etc..) and find themselves back in the same, or worse, scenario.
take care.. Sara
